Is the cliffside fractal still bugged or are we doing it wrong? We got that fractal at lvl 14 and while fighting the boss, an unsually huge amount of vets keeps spawning after the 1st hammer drop. We got wiped pretty bad and couldn’t advance.

Yes, the team is aware that Cliffside is still having problems and working on it, as we are getting some reports in the Game Bugs section (this one, for instance). I will proceed to close the thread an encourage you to keep on reporting in the already existing threads or though the in-game reporting tool.
